Ground-referencing
You can configure the SCXI-1305 for use with either
ground-referenced or non-referenced (floating) signal sources on a
per-channel basis using slide switches. When a channel is configured
for use with a non-referenced (floating) signal source, CH– is
connected to analog ground through a 100 kΩ resistor.
